Facebook falls, JPMorgan is up on earnings beat, Gamestop tumbles

Facebook (FB) shares are in focus, with the stock down around over 7% at the midday mark. The reason? CEO Mark Zuckerberg announced changes to the newsfeed to prioritize user content over that of publishers and brands. Investors are concerned people will spend less time on the site.

JPMorgan (JPM) shares are up after the bank reported earnings this morning, beating on both the top and bottom lines. It’s not all good news, however, as profits were hurt by a $2.4 billion charge stemming from Trump’s new tax law.

Gamestop (GME) shares are down more than 10% in midday trading. Despite reporting strong holiday sales growth, the video game retailer took a steep charge to its technology brands business, due to the iPhone X’s limited availability and AT&T’s new compensation structure.
